由清华大学、中国地质调查局青岛海洋地质研究所等单位组成的科考团队搭乘向阳红10号科考船于8月10日从深圳起航，对西太平洋进行深海热液科学考察。1经过18天的航程和7次探测器下潜作业，科考队在我国专属经济区西太平洋弧后盆地内精准锁定了一处大型高温活动热液区。1
喷口位于水下约700到1500米深度，喷口端元流体最高温度超过315℃。1矿体由黄铜矿、黄铁矿等重要经济矿物组成，伴生金和银的含量显著优于陆地矿床，其中伴生金的最高含量达15.4ppm，伴生银的最高含量达1271ppm。1
A scientific expedition led by Tsinghua University and the Qingdao Institute of Marine Geology under the China Geological Survey has identified a large-scale active hydrothermal vent area in the back-arc basin of the western Pacific within China's exclusive economic zone.1 The research vessel Xiangyanghong 10 departed from Shenzhen on August 10, embarking on an 18-day deep-sea hydrothermal survey mission.1 During the expedition, the team conducted seven submersible dives to explore and characterize the newly discovered field.1
The hydrothermal vents are located at depths between approximately 700 and 1,500 meters, with end-member fluid temperatures exceeding 315°C at the vent orifices.1 The mineral deposit comprises three large conical ore body structures composed primarily of chalcopyrite and pyrite—economically important minerals.1 Notably, the ore contains associated gold at concentrations reaching as high as 15.4 ppm and silver at levels up to 1,271 ppm, both significantly higher than typical terrestrial ore deposits.1
